SN'OW'` REMOVER FOR HIGHWAYS.

Application led December 11, 192th Serial No. 755,268.

To all 'whom t may concern.'

Be it known that we, JASPER MEIN and .ALBERT MEIN, citizens of theUnited States, residing at Osceola Township, in the county of Franklin,and State of Iowa, have inventedcertain new and useful Improvements inSnow Removers for Highways, of which the following is a specification.

Our invention relates to improvements in snow removers for highways orother places, and the object of our improvement is to supply for thisemployment a simply constructed and relatively inexpensive device forpropulsion by any desired meansand for operation of its movingmechanicalparts'by the same motor, to remove accumulated snow from roads and todischarge the same 'to the sides of the road out of the way of traffic.

This objectwe have accomplished by the means which are hereinafterdescribed and claimed, and which are illustrated in the accompanyingdrawings, it being understood that changes in the precise embodiment ofinvention herein disclosed can be made witlr in the scope of what isclaimed without departing from the spirit of the invention.

ln the annexed drawings:

Fig. 1 is a front elevation of our snow remover, with a part of the snowdischarger shown in section. Fig. 2 is a view, partly in 'side elevationand partly in longitudinal vertical section, with parts broken away, ofsaid snow remover as connected to and mounted on a tractor for bothforward propulsion and operative action upon a snow bank. Fig. 3 is arear elevation of the snow remover as separated from the tractor, andwith parts in section or broken away.

Qur device comprises snow removing and discharging` mechanism and meansmounted on a rigid frame structure havingconnected frame partsor beamsl, 2 and 3 which support a backing 5 made of plank or metal, the lat-terforming also the rear part of the dischargers 9. Forwardly projectingbeams i mounted on the yertical side beams or standards 2 carrytriangular side closure plates 7 and a downwardly inclined metal platetop', this structure supplying at the bottom a forwardly projectinginclinedprow for the device. Other vertical or substantially verticalstandards 10 have their lower ends pivota-lly mounted on the sides ofsaid prow 6-7 on bolts 11, and have slots 12 to receive pins 18A on theprow,.and secured by nut-s thereon to permit of forwardswinging of thestandards. Arms 14 are pivoted at their rear ends to the upper part ofthe frame just below the mouths of the hollow dischargers 9 to projectforwardly and having plates 15 mounted movably or slidably thereon. Theplates 15 have longitudinal slots 16 to adjustably receive threaded pins17 projecting from the arms and secured by end nuts. The forward partsof the plates 15 are secured to the tops of said standards 10 and haveapertured bearings registering with other apertured bearings in thestandards to receive the end parts of a rotatable shaft 18, on eachside, the innerend of each short shaft 18 having a hub secured thereonwith spider arms 2O inclosed in a circumferential ringl 19. The spiderspokes `20 are connected by means of the bars 21 which thus extendacross the front of the upper end of the device in spaced relation. Theposition of the shafts can be adjusted to somewhat lower the shafts 18and set them more forwardly by use of the adjusting means shown.

The use of the above described rotatable open wheel as it is rotated inthe direction indicated by the arrow downwardly, is to thrust down andrearwardly the upper part of a relatively high snow bank encountered toprevent the snow being forced over the top of the dischargers 9 where itwould fill the air behind the device and interfere with the propulsionthereof by the following` tractor 44. It also delivers this top part ofthe snow bank directly to the pair of rapidly rotating large deliverydisks 51, insuring the complete reception by the device of the snowahead and its discharge through the funnels or open vconduits 8-9 toopposite sides of the device or the road.

The said snow wheel and the disks 51 are rotated simultaneously by themeans now to be described. The device as a whole is pio polled forwardlyby some appropriate means such as the tractor 411. To the crank-shaft ofthe motor of the tractor (not'shown) prolonged forwardly in anv desiredway, is slidably connected a sleeve member-38 havinga clutclrgroovewhich receives'the forks `39 of 'a lever of the bell-crank type mediallypivoted at Li() and having its upper limbpivotally connected to thevforward extremity ,ofaf connecting-rod 41.' The rear end of thisconnecting-rod is pivotally connected to a hand-lever 42' pivoted at itslower end to the tractor frame andhaving `at,manually controllable detent for releasably engaging either' of two notches on a rack-sector43:." By this means a cone-clutch member 37 may be shifted into or out,of engagement with an internally coned friction member 36 nonslidablybut rotatably mounted on the `eXtension-shaft part before referred to,the clutch-member 3S being non-rotatable on the shaft. vThus thebevel-gear 34 rigid with said member 36 may be rotated in one direction.

Referring to Fig. 3, the numeral 33 denotes another bevel-gear in meshkwith the gear 3l and inonntedon a transverse counter-shaft 31. At eachend of the shaft 31 mounted in bearings as at32 are the sprocket-wheels30 carrying thev sprocketchains 29 whose upper parts are passed aboutsprocket-wheels 2S mounted on short shafts 26 in spaced bearing-boxes27. On theshafts 26 are also mounted other like sprocket-wheels 2 5carryingthe -lower parts of sprocket-chafins` 28 which latter arecarried forwardly slopingly through apertures 24 inthe backing' to bemounted around the like sprocket-wheels which are mounted at 22 ontheshort shaft parts 18 of the snow-wheel 19. 7h-en the shaft 35 is rotatedin the proper direction by the tractor moto as is indicated in Figq bythe arrow, the said drivingl connections act vto rotate said snow-wheelin the direction of the arrow, that is, forwardly and downwardly toengage and draw the top of the d rift against the rotating disks 51.

The disks 51 are rotated in opposite directions and itoward each otherby the following driving connections.

' Lilie bevel-gears 8 are mounted-on the shaft 31 on opposite sides ofrthe middle gears 3l and but in reversed positions, and inteiinesh withbeifelgears li) on short shafts not shown mounted in bracketedbearing-boxes on `the rear .face of said -back- .iiigplate v5l On thesaine shafts are nziounted like sprocket-wheels carrying the lower.parts yof vsprocket-chains whose upper 'parts' are placed around`sprocket-wheels mounted on the shafts 5() which carry the said 'diskslbefor'e the backing-plate 5. It-'will'be seen that the.y arrowsindicate that the disks are bythe said mea-nsrotated reverselylReferring to said Fig. 1 a smallerinetal aia; '52 i asienta 'by vtoits;apta 'therefwaifd face k,of -each rdisk coiicen'trically l orcoavixially tegral iadia'l"raise/dv and steden tendente ses .fofede-11i' directed gie-b s ,5S-.secured by bolts t 'tliefdisk 2 as alsotov they: fern "RdIYPiQiQEtbilo'V igt Eng as pir ier and (1101113y ti iI disk f Tlf@ e einem@ .its ,attenere ses@ and kServes tiene' een esttbl@ mounted on the rtractor #f4 lin any desired wayY and by meansof`diifereiit bonnections. I have shown this frame carried on the frontofthe tractor rigidly by mean's of divergent bracket-bars 46' an-d 57 atVeach side, the lower secured by bolts 47 to the frame standards and theupper bars secured to parts of the ybrackets 5S.

In operation when the device is propelled against a bank of snow, theprow'G pene# trates the drift limmediately above the road surface,Y theOppositely rotating disks with their flanged Iblades 56 planing off.thin layers of the snow'as guided b the prow and including snow pushedc ownwardly from the top of the bank'against them `by the snow-wheel 1S)and its pushing bars 21. All fthe snow infront of the device'is thusbroken' up7 gathered. and delivered into th-e openings S of thedischargers 9, -the snow being thrown from the latter to oppositeI sidesof the device'or of the road. As the quantity of snow cutandinoved atanyy in- `st-'ant is relatively small, much power is not required, andby this means ,the road can be quickly and completely cleared of snowaccumulations. The scale of size mayk be yaried of the disks 51 and theother parts, so that a wide enough path can be made at one traverse foruse by passing vehicles.`

Having described our inif'ention, what we claim asY new and desire tosecure by Letters Patent, is:

1. In a snow remover, in combination, a transportable struct-ure havinga forwardly projecting inclined prow at its base, a pailof like wheelsabove the top of the rear of said prow rotatable revers'ely downwardlyxtoward each other on longitudinal axes. a chute having a single openinginto which both disks deliver medially, and a rotatable device withtransverse 'horizontal blades supportedswingingly adjnstably above theforward upper 4parts of saiddisks to engage theto'ps of drifts and planeand propel thin layers thereof downwardly toward the disks.
